I am installing two 12 V 100w solar panels to a Renogy DCC50s 12v 50A DC-DC Solar controller. The solar controller manual says that it has a maximum of 25 V input. When I wire the panels in series I get 39 V so I assume I have to wire these panels in parallel to get the voltage below 25 V. Or am...

Hey all, I decided to just isolate the two system and if the starting battery ever does go bad I have a jump starting unit that I will use. The last question I have is can I connect the negative of the lithium battery to the same negative bus bar that the AGM battery is connected to? The...

I just bought a houseboat and redoing all the wiring and installing a new 300amp lithium house battery. Currently the outboard (OB) via a stator charger which currently charges the starting battery (AGM). There is an auxiliary charging line that I can connect from my OB which is designed to...

Thanks all for the input. Good Package, who is YT? Sorry if that is a stupid question. And what other vendor are you speaking of.

I asked Ampere Time why their 400ah was so much more money than getting (2) 200ah batteries and wiring in parallel and this is their response. I need help in the translation The reason why a single 400Ah battery is a little more expensive than 2*200Ah connected in parallel, that because there...

It appears I need to give a little more info. This is in a RV, I mostly dry camp (boondock) and at the most a week. My 272ah battery can last me that whole time without going below 20% capacity. If I plan on going for more than a week I will bring my generator and charger the battery back up...

Mike, sorry if this is a stupid question but this is my first lithium battery so a little (OK alot) green. The Overkill BMS manual says to set the "Full charge voltage" at 3.5 so I that would be the target volts you mentioned correct? Since my AIMS converter is NOT programmable I think I will...

I am at a campground with poor cell service so hopefully this comes through

Thanks all, I have a AIMS 12V 75A converter and it does not allow me to change the absorption as suggested it has preset settings. I guess I could set the AIMS to a Gel type battery (see attached image), that is the closest to the suggestions

I installed a12V Lishen 280 Ah (acutally 272Ah) with a Overkill 120A 4S BMS. From what I have read the absorption should be 14.5V, Float at 13.6, Inverter cut-off at 10.7, over voltage max at 3.65 or 14.6, undervoltage at 2.8 or 10V+. Per Will he suggests not going below 10% and charging to...

I want to install my inverter in the same compartment as my lithium battery, is that OK? I know that that is not something you would do if you had a lead acid battery. Thanks all

I built a 100ha Fortune LiFePO4 with a Overkill Solar 12v 4S 120A BMS with bluetooth. I also bought/installed a cheap AiLi battery monitor. I sold that RV and bought another one so I am back to upgrading the new system to a 280ah LiFePO4 battery system. So the question is, since the Overkill...

I have not installed the new ATS and inverter yet but will let you know when I do

I It is a 12V system.

To update all on what happened, I called AIMS and got a different tech and he said it was because I had old capacitors on my AC unit. that still made no sense to me since I was connected to shore power and the transfer switch on the unit should have just passed that power directly through. So...

This is the fuse that I installed https://smile.amazon.com/gp/product/B079ZK1GYL/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 and I used 3/0 wire since that is what I had in the shop. Also the run from the unit to the battery is 12". thanks for your input

I installed a AIMS 2500w Inverter/charger/transfer switch unit in my RV and it blew the 250amp bolt on fuse I had on my new Fortune 100ah lithium battery. I was connected to shore power and running the AC and it had been running for about an hour before it blew. I thought that was odd since...

Actually the first one (lower one) is a 40a breaker and the second one (upper one) is a 30a breaker

Thanks again Tictag for you help. I don't know why Renogy doesn't list it that way.

Thanks all, I will check this out next time I am at the rig on Friday

I have a Renogy Rover 60 Amp 12V/24V/36V/48V MPPT Solar Controller and am unclear whether they will work with this controller. From what I can tell it only works with those specific volts.

Mopat you gave me a clue, thanks. I just noticed the heavier red wire coming off the first breaker (which is probably the bigger breaker, need to verify that) but I don't know where that one goes. So I could be wrong and the upper red wire labeled going to the distr panel could be incorrectly...

Are these Panels any good? They are an hour drive from me https://www.ebay.com/itm/260-WATT-REC-PEAK-ENERGY-Z-LINK-SERIES-REC260PE-Z-LINK-SOLAR-PANEL-/293260378380 Thanks all

I just bought this 5th wheel and noticed that the wire coming from the battery goes to beaker and then to another breaker before heading to the distribution panel. Why is that? I have attached a photo and the breakers in question are in the yellow box. Thanks all

Thanks TicTag, those were things I remembered when I upgraded my boat electrical system but it doesn't hurt to be reminded. There are a lot of parts in a system like this so things can be missed. Thanks again sir

HRTKD, I took your advise and went with a Inverter, ATS, Charger, & Converter in one box. I got the AIMS 2500w green box on sale for $454. So I have revised my schematic once again. Tictag, would love to get the Victron but I am putting all this into a 20 yr old rig so I am going somewhat...

I have the same question as the original poster. I just bought an RV and the existing Converter is a WFCO WF-8855 and am wondering if it will work with 100ah lithium battery I want to get. I have attached the charging parameters of the WFCO. If not I was thinking of replacing it with a...

SCClockDr you the DROK DC 0-300V 200A STN LCD Display Digital Multimeter Voltage Ampere Power Energy Ammeter Voltmeter Battery Volt Amp Meter AH Monitor Panel with Hall Sensor so what do you think of it?

I do not have an onboard generator and do not plan on adding one. Good catch on the converter, thanks a bunch!! See revised schematic attached. I also reduced the fuse from the panels to 40a, I will increase the size when I added the future panels Thanks HRTKD for your input

OK after all the input this is what I settled on at least at this point :- ) I have include a schematic of what I am doing on my 5th wheel for review and comments. Again, thanks everyone for your comments Parts of the system Solar Panels: Rich Solar 100A panels. I heard what other said to go...

Thanks HRTKD, I just sold a boat where I also had 220AH of flooded lead acid batteries and a 225w solar panel. And ran a 12v refrig and had no issues in the summer. My boat was heated by a propane fireplace that only had a computer fan so not much power there. So the heater on an RV is a...

So this one would work.....right? https://www.amazon.com/EPEVER-Controller-Lead-Acid-Lithium-Support/dp/B07NVDJFD4/ref=sr_1_2?dchild=1&keywords=epever+MT50+module&qid=1594143830&s=lawn-garden&sr=1-2

Will in his book says this; "Smaller solar panels are inherently stronger and thus, recommended if you mount them on the roof of a moving vehicle. 100W panels are the best size. They are strong, cheap, easy to find and easy to install." And another thoughts is redundancy. If you lose on 335w...

Why do you prefer the EPSOLAR 40A over the Vicron? And what model EPSOLAR there seems to be two 40A models. Thanks
